Concept explainers
(a)
Interpretation:
Each of the given disubstituted cyclohexane is to be identified as either a cis or trans isomer.
Concept introduction:
In case of disubstituted cyclohexane, the substituents which are on the opposite side of the ring are trans to each other. Substituents are said to be cis, if they lie on the same side of the ring. Substituents that are trans to each other in one chair conformation remains trans after the chair flip and substituents which are cis to each other remain cis.
(b)
Interpretation:
Each of the given disubstituted cyclohexane is to be identified as either a cis or trans isomer.
Concept introduction:
In case of disubstituted cyclohexane, the substituents which are on the opposite side of the ring are trans to each other. Substituents are said to be cis, if they lie on the same side of the ring. Substituents that are trans to each other in one chair conformation remains trans after the chair flip and substituents which are cis to each other remain cis.
(c)
Interpretation:
Each of the given disubstituted cyclohexane is to be identified as either a cis or trans isomer.
Concept introduction:
In case of disubstituted cyclohexane, the substituents which are on the opposite side of the ring are trans to each other. Substituents are said to be cis, if they lie on the same side of the ring. Substituents that are trans to each other in one chair conformation remains trans after the chair flip and substituents which are cis to each other remain cis.
(d)
Interpretation:
Each of the given disubstituted cyclohexane is to be identified as either a cis or trans isomer.
Concept introduction:
In case of disubstituted cyclohexane, the substituents which are on the opposite side of the ring are trans to each other. Substituents are said to be cis, if they lie on the same side of the ring. Substituents that are trans to each other in one chair conformation remains trans after the chair flip and substituents which are cis to each other remain cis.
(e)
Interpretation:
Each of the given disubstituted cyclohexane is to be identified as either a cis or trans isomer.
Concept introduction:
In case of disubstituted cyclohexane, the substituents which are on the opposite side of the ring are trans to each other. Substituents are said to be cis, if they lie on the same side of the ring. Substituents that are trans to each other in one chair conformation remains trans after the chair flip and substituents which are cis to each other remain cis.
(f)
Interpretation:
Each of the given disubstituted cyclohexane is to be identified as either a cis or trans isomer.
Concept introduction:
In case of disubstituted cyclohexane, the substituents which are on the opposite side of the ring are trans to each other. Substituents are said to be cis, if they lie on the same side of the ring. Substituents that are trans to each other in one chair conformation remains trans after the chair flip and substituents which are cis to each other remain cis.
